What you would be responsible for:
  • Apply computational biology and machine learning tools to generate insights and hypotheses from high-dimensional molecular datasets, with a focus on large-scale scRNA-seq & snRNA-seq disease atlases.
  • Develop & lead data analysis strategies and ideation across diverse biological and clinically relevant projects with internal and external stakeholders.
  • Act as the computational biology co-lead on drug programs, working with experimental scientists to ensure that study designs & data are properly interrogated to deliver high value readouts.
  • Present your results in an interdisciplinary team of biologists, chemists, clinicians, technologists, and other machine learning colleagues in meetings covering cross-functional project teams, functional teams, to whole company and management meetings.


What experiences will you need:

  • Ph.D. or equivalent in biology, computational biology, or related scientific field.
  • 4+ years of relevant industry experience.
  • Extensive experience in analyzing and deriving hypothesis from single-cell transcriptomic data, preferably also with large-scale single-cell atlases.
  • Demonstrated scientific understanding of molecular and systems biology, diverse molecular data types, and analysis tools.
  • Practical programming and scripting skills, preferably in Python.
  • Fast learner, analytical thinker, creative, "hands-on", strong communication skills.

  • Go all out: We work quickly and with conviction.

Company Summary: Cellarity's mission is to fundamentally redesign the way drugs are created for the sake of bringing new hope to patients. By shifting the focus from a single target to the underlying cellular dysfunction, we unravel the complexity of disease biology and create medicines that were never before possible. The company has developed unique capabilities that link biology and chemistry with high dimensional -omic data from which we design medicines against the cellular signature of disease. The Cellarity platform allows us to uncover new biology in diseases even in the absence of known causal targets. The company has drug discovery programs underway in several disease areas, including metabolic disease, hematology, and immunology. Cellarity's goal is to grow into a fully integrated next generation Biotech company driving a new age in drug creation.
